Ive had e3s for 3 years now in the cuda they are great, run them in a garden pulling tractor no problems. They have a lifetime warrenty on them I sent 1 pkg back they gave me new ones.
Lifetime warrantee and they back it up. This is enough to convince me to try the E3. It will go in my 3.8 litre V6 in my 00 Caravan. Onboard mileage calculator makes it very easy to track improvements in gas mileage,so I'll let you guy's know either way.
